Abaylon- it sounds like the grandparents will try anything so that you don't see them. Like was mentioned, dog attacks are way more common than snake attacks. As was also mentioned, if you can prove with pictures they are safely away from the children, then you should be fine. Even if SS has to come to your house and see where they are kept, then this is fine. It's bull crap, but people are ignorant. Even cats can be dangerous.
